More Information
Summary:A diaphragm valve is provided which can be used both with corrosive liquids without valve component degradation and with chemically pure liquids without deleteriously affecting the liquids' purity. The valve incorporates a valve body having at least one inlet and at least one outlet, with a valve seat between each inlet and outlet. A pair of spaced-apart diaphragms are provided which are in contact with the fluid flowing through the valve. A poppet assembly, which extends between the diaphragms, incorporates a valve stem with a valve plug on one or both ends which engages an associated valve seat. A leak detection port is provided to detect liquids which may leak through either one of the two diaphragms.
